Explain how you can find the measure of angle 12?
How can you find the measure of angle 1?

Let's say you know the measure of angle 10. Let's make it 120 degrees.

Since it looks like you're going through a traversals unit (or something that includes traversals), you know that angle 10 and angle 8 are the same, which means they are both 120 degrees.

Now, since a line is 180 degrees on one side, you have to subtract 180-120 to find angle 7, which is 60.

Using the exterior-interior rule (I don't know the name), you know that angle 7 is equal to angle 1, which gets you 60.

Angle 1: 60 degrees.

You can do the same thing with another angle to find 12, or continue with this scenario with angle 10 being 120 degrees.
